as indicated in Fig. 1, the separation of the top sections while thepedestal .sections remain engaged with each other, being limited by stopbolts 19 on the guides 14, which engage complemental stop shoulders onthe slides 17 atlixed to the top sections. Provision is thus made for aminimum extension of the table, the arrangement being preferably suchthat when the top sections Aare separated to the maximum extentpermitted while the pedestal sections are locked f together, space isafforded suflicient to pereach support as here shown, including endconstruct-ion. The

members 20 attached to the top sections 1G and projecting inwardlytherefrom, and an intermediate member 21 slidingly engaged with themembers 20the said members having complemental tongues and grooves whichpermit the extension and contraction of the eaf supports afforded bysaid members, and

shown'in Fig. 2.

VTwo independent locking mechanisms are provided, one for detachablylocking the pedestahsections together and the other for detachablylocking the'top sections together. These mechanisms mayv be 4of anysuitable specific locking devices here shown are set forth and claimedin another application filed concurrently herewith by Edgar L. Marston,and the same are noty therefore specifically claimed by me.

The pedestal locking mechanism here shown includes a rock-shaft 23journaled in a bearing'24 affixed to one of the edestal sections 12, adisk 25afiixed to sai rock-shaft and having astud 26Iwhich is eccentricto the shaft 23, a hook 27 pivoted to swing on the, stud 26, and a loopdicated bythe arrow in Fig.l 5, the hook is4 firstf'moved backwardlyfrom. its bearing on `,the floop 28, and is then swung laterally outoreye 28 affixed to. the opposite pedestal section in position, toy

drawing tlilpedestal sections together, andA holding them in closecontact with each other. The rock-shaft 23 extends through the upperend` of the pedestal, and is provided with a hand wheel 29, by which itmay be rotated, access to the hand Wheel being provided. by separatingthe top sections 16..

The mechanism here shown for detachably ,locking the top sectionstogether includesa loop or eye 30 attached to the under side of one ofthe top sections 16, a bell-crank lever 31 having a slot 32 throughwhich passes a fulcrum stud 33 attached to the opposite top A section16, the lever 31 being adapted both to swing and to move endwise on thefulcrum stud, and provided v with a hook 34 adapted to engage theloop-30, an operating lever 35 fulcrumed at 3.6.to an ear aiiixe to theunder side of the top section 16 which supports 4the lever 31,.and aconnecting'rod 37 engraved at 38 with one arm of the lever 31,andzliaving at its opposite end a clip 39 which is pivoted at 40 to thelever 35, the arrangement being such vthat when the lever 35 is in theposition shown in Figs. 3 and 6.

thehook 34 ofthe lever is within the loop'l 30, and presses against oneend of the sa1d` loop with sufficient force to rdraw and hold themeet-ing edges of the top sections-1G` closely together. lVhen the lever35 is swuiw downwardly from the .position shown in F 1g. 3, thebell-cran'ltlever 31 is first moved endwise to remove the hook 34 fromits bearing on the loop 30, ,and 1s then swung laterally, wlthdrawingthe l hook from the loop. 'The change of 'position of the lever 35 tothe position shown in F ig. causes the hook 34 to first swing into theloop, and then to move endwise and exert sufficient pressure ontheloop-'to'force the top sections 16 firmly together.

It .will be seen from the foregoingthat provision is made for partlyextendin the table top without separatingl the pe estal sections, andfor giving the ta le top a maximum extension by the separation of thepedestal sections. y

Each of the stop bolts 19 and 22 is yieldingly held in its operativeposition by a spring42, and is provided with a shank or handle 43whereby it may be manually retracted from engagement with thecorrespondin shoulder to 'permit the separation lof `the s ides 17 fromthe guide members 14 and of the end members 20 of the telescopicsupports from the intermediate members 21. Provision is thus made forventirely separating the slides 17 from the guidemembers K' 14 and theend members 20- from' the inter:

' provided with beveled faces arranged to re- 'permanent top sections,or

leaves,

tract the bolts when the pedestal sections and top sections are movedtoward each other to contract the table. The said beveled faces .andstop shoulders, against which the bolts abut, form recesses into whichthe bolts are projected by their spri11gs \vhen the pedestal sectionsand the topv sections reach their maximum extension. A further extensionto disconnect the pedestal sections from each other land the topsections from each other and from the pedestal sections,y is permittedby retracting thebolts 19 and 2Q.

It will be seen that tivo sets of telescopic `supports are provided, thesupports of one* set being composed of the uide members 14 and slides`17, and supportingr the permanent sections of the table top, Whilethesupports of the other set are composed of the end members 20 andintermediate members 21, and support the removable leaves when thepedestal sections and their attached slide members 1'1 are respectivelyseparated. It will also be seen that each support has complemental stopswhich normally limit the extension of the support, and are separable topermit the entire separation of its inembers by a continuation of theextension of the support. A top support of this character is believed tobe` broadly new in an extension table, and it is therefore my intentionto' be understood as claiming broadly a support or a set of supportsthus characterized, Whether employed for supporting the the removable orboth the permanent sections and leaves.` I also believe myself 4to bethe first to provide one of the members of the support with a fixed stopshoulder and a beveled face adjacent thereto, and another mem- `-berWith a spring-pressed bolt adapted to be retracted by said face when thesupport is contracted, and to be manually retracted to permit theseparation of the members.

By providing the knock-down construe-- tion herein described, I producea pedestalextension dining table in Which it is possible to remove Ythesections comprising` one top and to substitute therefor another top ofdifferent diameter or design, this being accomplished Without theremoval of such perma- Y nent fastenings as screws or the like. Vhile Ihave described the manually-operable deviceswhich normally limit the'separating movement of the top sections as being of the nature ofspring-pressed bolts, neverthelessl I do not desire to limit myselfthereto as their equivalents may be substituted therefor. Moreovervarious other changes of similar character may be made Without departingfrom the spirit and scope of the invention. V
